A container for holding material such as ice-cream, which can be readily fabricated at a local container-filling plant, out of rolls of stock material and other easily stored and transported components. The container includes a sheet of kraft paper with thermoplastic coatings and a pair of U-shaped edgings extending along opposite sides, the sheet formed in the shape of a cylinder and having ends which are overlapped and heat welded together. A bottom cover includes a U-shaped periphery that extends around the lower edging, and which has a pointed inwardly-directed boss that securely engages a corresponding bead on the edging, the engagement being tightened when the container is filled with material that deflects the bottom cover downwardly. The top cover includes a beaded rim extending around the cylinder in a close fit therewith, and which can slide up to accommodate expansion of ice cream which expands as it freezes.
